The forecasting model that assumes previous time periods have some influence on future sales, but the influence varies by time period, is
A:moving average.
B:weighted moving average.
C:historical analogy.
D:mean absolute deviation.
E:exponential smoothing.
Homework Answers
The correct answer is moving average because this technique considers the underlying pattern of a historical data set for establishing an estimation of future sales values. Some of the most common types of moving average are 3 and 5 month moving averages, where 3 month moving average is computed by taking into account the average of current and past two months' revenues. On the other hand, 5 month moving average forecasts revenue starting the fifth period. In this way, it can be said that this forecasting model is influenced by the time period.

1. Exercise 5.1 The forecasting staff for the Prizer Corporation has developed a model to predict sales of its air-cushioned-ride snowmobiles. The model specifies that sales, S, vary jointly with disposable personal income, Y, and the population between ages 15 and 40,Z, and inversely with the price of the snowmobiles, P. Based on past data, the best estimate of this relationship is: where k has been estimated (from past data) to equal 100 If Y $13,000, Z- $1,200, and P...

You are doing an internship with Macy’s and are tasked with forecasting sales so that you can make inventory orders. You have weekly sales data for men’s dress shirts in your store from each of the past six weeks. You decide to try both a 3-period moving average and exponential smoothing with λ = 0.7 to see which model is more accurate and then use that one to make forecasts. The sales data is shown below.
